Back to original languageAbout Ignacio
I am a software developer specializing in Java, Spring, microservices, and hexagonal architecture, with experience in high-level projects for banking, telecommunications, and large companies. I help companies improve, scale, and maintain their systems by developing robust, clean, and growth-ready solutions.
I differentiate myself through my ability to work in complex environments, both monolithic and distributed, integrating new components, optimizing performance, resolving critical incidents, and modernizing existing applications. I master complete development cycles under agile methodologies (Scrum) and CI/CD pipelines.
I have managed and developed projects such as:
• Microservices with Spring Boot, Spring Batch, and OSGi
• Secure REST APIs with Swagger, Spring Security, and JWT
• Full-stack evolutions and maintenance with Java, Thymeleaf, jQuery, and Bootstrap
• Integrations in banking architectures (immediate payments, Bizum, APX/ASO)
• Backend systems with Oracle, Prisma, PostgreSQL
• Automation, monitoring, and deployments with Git, Bitbucket, Jenkins, and Kibana
My approach combines technical solidity + problem-solving ability + maintainable code, adding value in both new functionalities and system stability.
